Asection of dna is transcribed to produce a strand of mrna. the original dna has the following sequence of nitrogen bases:
atg gcc caa tcg tga
due to a point mutation, transcription results in the mrna sequence of:
uac cgg guu agu acu
transcription in this case will result in
a) a mutated protein that is potentially harmful.
b) the correct sequence of amino acids in the synthesized protein.
c) a situation where protein synthesis does not "stop" translating.
d) the incorrect sequence of amino acids in the synthesized protein.

Which of the following descriptions of proteins are true? i. proteins can have different sequences of amino acids. ii. proteins can have different shapes. iii. proteins can have different numbers of amino acids. a. only i and ii are true. b. only ii and iii are true. c. only i and iii are true. d. i and ii and iii are all true. e. none are true statements

For a to be healthy, it has to have lots of different kinds of plants and animals. all of the different types of plants and animals in an ecosystem. name four types of ecosystems from those listed in the video. b) c) d) most living things live here. all living things depend on how an ecosystem like a game of sticks? why should we build new buildings on existing land? name four extinct species from those listed in the video. b) c) d) the best way to wipe out a species is to the largest ecosystem in the world is this percent of the world is covered by water. how many of all species in the world live in the ocean? list five things you can do to increase biodiversity. b) c) d) e) how many species are we losing per hour?

Which of the following is not associated with invasive species?
